回転炉内の粒子軸方向混合と滞留時間分布

抄録

Residence time distributions of particles in a horizontally rotating cylinder were theoretically and experimentally studied. A mathematical model of the axial dispersion of particles was analytically solved and the following expression for their residence time distribution was obtained:
Dimensionless Peclet number as a function of variances in residence time distribution was given as fol-lows:
Measurements were based on an impulse response method of tracers into spherical alumina particles stream through a rotary cylinder which is made of vinyl chloride resin.
An empirical correlation among Peclet number, operational conditions, and geometrical factors was determined:
Upon examinations of effects of the revolution rate on the axial dispersion coefficient, it was shown that the latter was directly proportional to the former.
